Association of Dietary Intake of Flavonols With Changes in Global Cognition and Several Cognitive Abilities

APOE-ɛ4, late life cognitive activity, physical activity, and smoking, total flavonol intake was associated with slower decline in global cognition β estimate=0.004 (95% CI=0.001, 0.006), episodic memory β=0.004 (95% CI: 0.002, 0.006), semantic memory β=0.003 (95% CI: 0.001, 0.007), perceptual speed β=0.003 (95% CI: 0.001, 0.004), and working memory β=0.003 (95% CI: 0.001, 0.005) and …

Temporal patterns of energy intake and cognitive function and its decline: a community-based cohort study in China

Dear Editor,Worldwide, around 55 million people had prevalent dementia in 2019, which is expected to triple by 2050, especially in low- and middle-income countries. Lacking timely diagnosis and limited effective treatment for dementia make identifying risk factors crucial for its early prevention, among which dietary factors have received increasing attention.Recently, accumulating evidence from population-based studies …

Fitness tracking reveals task-specific associations between memory, mental health, and physical activity

Physical activity can benefit both physical and mental well-being. Different forms of exercise (e.g., aerobic versus anaerobic; running versus walking, swimming, or yoga; high-intensity interval training versus endurance workouts; etc.) impact physical fitness in different ways. For example, running may substantially impact leg and heart strength but only moderately impact arm strength. We hypothesized that …

Effects of cocoa extract and a multivitamin on cognitive function: A randomized clinical trial

IntroductionDietary supplements are touted for cognitive protection, but supporting evidence is mixed. COSMOS-Mind tested whether daily administration of cocoa extract (containing 500 mg/day flavanols) versus placebo and a commercial multivitamin-mineral (MVM) versus placebo improved cognition in older women and men.MethodsCOSMOS-Mind, a large randomized two-by-two factorial 3-year trial, assessed cognition by telephone at baseline and annually. The …

Spontaneous discovery of novel task solutions in children

Children often perform worse than adults on tasks that require focused attention. While this is commonly regarded as a sign of incomplete cognitive development, a broader attentional focus could also endow children with the ability to find novel solutions to a given task. To test this idea, we investigated children’s ability to discover and use …
